10.1.4
The following modes of operation are specific to the MSCAN. See
for details.
10.2
The MSCAN uses two external pins:
10.2.1
RXCAN is the MSCAN receiver input pin.
10.2.2
TXCAN is the MSCAN transmitter output pin. The TXCAN output pin represents the logic level on the
CAN bus:
10.2.3
A typical CAN system with MSCAN is shown in
to the CAN bus lines through a transceiver device. The transceiver is capable of driving the large current
needed for the CAN bus and has current protection against defective CAN or defective stations.
